Mamas //V50/v United States Patent 3,431,013 COMBINATION ROUND AND HEXAGONAL PUSHER GRIPS Nickolas Hoyson, 321 Academy St., Carnegie, Pa. 15106 Filed Oct. 5, 1967, Ser. No. 672,901 US. 'Cl. 294102 Int. Cl. B6511 /14 2 Claims ABSTRACT OF THE DISCLOSURE The present invention relates to improved combination round and hexagonal pusher grips, and includes a grip means having a flat side down so that the edges of the bars may fit into V-slots of the grips.

An object therefore of the present invention is to provide ease and facility in handling round and hexagonal or otherwise irregular contoured bars by pusher grips.

The above and other objects and advantages of the invention will become apparent upon full consideration of the following detailed description and accompanying drawings in which:

FIG. 1 is a side elevation view of the combination round and hexagonal pusher grips;

FIG. 2 is a cross-sectional view taken along lines 22 of FIG. 1;

FIG. 3 is a cross-sectional view taken along lines 3--3 of FIG. 1;

FIG. 4 is a cross-sectional view taken along lines 4-4 of FIG. 1;

FIG. 5 is a generally perspective view of one of the elements otherwise illustrated in FIG. 1, such as the one on the left-hand side thereof; and

FIG. 6 is a generally perspective view of a T-bar.

Referring now to the drawings, there is shown a combination round and hexagonal pusher grip means 10 comprising a pair of prismatic bodies 12, 14 which are disposed along a symmetrical axis (not shown) but parallel generally to lines 3-3 of FIG. 1, and in which one end 16, 18 of the pair of bodies is tapered forming a tapered surface 20, 22, respectively.

There is a beveled edge 30, 32 along the tapered surfaces, and there is a transverse slot 36, 38 which is perpendicular to the axis mentioned above, and there is a further slot 40, 42 which extends skew to said axis and is parallel to said beveled edge.

It is therefore seen that the grips make it much easier for the operator of a machine to handle hexagonal-shaped 3,431,013 Patented Mar. 4, 1969 cold drawn steel bars of all sizes, and in which the operator does not have to turn the hexagon edge to put it in dies. By means of the present invention, there may be three ibars at a time inserted into dies which otherwise is difficult to do without the practice of the present invention. The present invention eliminates this difficulty by putting the bars with fiat side down and edges into the V-slotted areas of the grips, and in which the prior art means provide for only two bars to be handled at a time. Therefore by the present invention, three bars at one time may be handled with much less effort and this results in an increase in production with better quality.

The transverse slots are for the T-bar 50. As is known, it is placed in the slots 36, 38 to bring the pusher grips 10 back and forth. When pushing the T-bar 50 closes in on the hexagonal or round bar to clamp it tight. When the pushing to the desired length is completed, the automatic switch (not shown) is tripped, the grips are released and the T-bar 50 releases the grips 10 to open. When the pushing begins, the T-bar 50 pulls the grips back and closes tight; when pushed far enough, the T-bar releases the grip. This could be applied to drawing four at one time.

Nuts are secured on the end (not shown) which is inserted through a yoke. This is accomplished in operation by hydraulic pressure. The grips 10 must have the threading or teeth 56, as shown in FIG. 3.

Additional embodiments of the invention in this specification 'will occur to others and therefore it is intended that the scope of the invention be limited only by the appended claims and not by the embodiment described hereinabove. Accordingly, reference should be made to the following claims in determining the full scope of the invention.

What is claimed is:

1. A combination pusher grip means for round and hexagonal bars comprising a prismatic pair of bodies arranged along a symmetric axis, one end of said pair being tapered and each having a beveled edge along the outside thereof, a transverse slot perpendicular to said axis, the mating surfaces between said pair of bodies forming a round curved surface for receiving in clamping relation a round bar, said round curved surface having at its bottom a grooved recess for receiving in clamping relation an edge of a hexagonal bar, and teeth along the curved surfaces to grip said bar.

2 The invention according to claim 1 wherein there is provided a slot of small dimensions skew to said axis and parallel to said beveled edge.
